Sultan Ismail,
Since I am in First Class all the time, I count the pilots as they enter the Flight Deck and make sure neither of them sneak off.
Now if what you are saying is that if the PAX did not know there was nobody up there it would make no difference. If I got off an airplane and found out there had been no pilots up there quite a few of the airline employees would feel the brunt of my foot before airport security got hold of me.
